JOHNSON BREER, OF RICE, TEXAS.

FLOUR SIETER.

Application filed January 24, 179,22. Serial No. 531,470.

To @ZZ fr/tom 'it may concern.'

Be it known that l, JOHNSON BREWER, a citizen of United States,residing at Rice, in the county of Navarro, State of Texas, have invented certain new and useful Improvements in Flour Sifters;v and I do hereby declare the following to be a full,

l clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates tofnew and useful improvements in flour sifting machines, and is an improvement on my prior Patent No. 1,390,334, issued September 13th, 1921.

One object of the invention is to provide this device with a hopper and means for feeding material from the hopper to the sifting drum.

Another object is` to provide means for supporting a feed shaft whichvis operable by the rotatablesifting drum and a novel connecting conduit between the hopper and the drum.

Other objects will be apparent from the following description when taken in connection with the accompanying drawings.

ln the drawings:

Figure 1 is a side elevation of a flour sifter made in accordance with my invention and partly broken away. i

Figure 2 is a vertical longitudinal central sectional view through the device.

Referring particularly to the accompanying drawing, 10 represents a box-like structure supported on the legs 11, and having a discharge spout 12 in the bottom thereof, beneath which is to be placed a bag or other receptacle to receive the sifted flour. A hinged lid 13, is carried by the body of the box 10, to permit access to the interior thereof.

. Mounted in one end of the box is a hopper 14, and in one wall of the hopper there is formed an opening 15, communicating with the interior of the box 10. Disposed longitudinally through the center of the box 10, and the lower portion ofthe hopper 14, is a shaft 16, with the end within the hopper projecting beyond the outer wall of the hopper where it is provided with a fiange 17, which is secured to the outer face of the hopper wall, thus holding the shaft firmly against rotation. Disposed through the other end of the box 10, is a crank 18, and formed in the portion.y of the .crank which is supported within the wall is a socket 19, which rotatably supports the adjacent end of the shaft' 16.

Rotatably supported on the shaft 16, within the hopper, and vprojecting a short distance within the box 10, is a hollow shaft 20, said shaft having' a spiral feed rib 2l formed thereon. Disposed within the box 10, is the sifting' drum 22, the shaft16 extending longitudinally through the center thereof. Extending between the hopper and the adjacentend of the drum, and surrounding the shaft 20, is a sleeve 23, of sufficient greater diameter than the shaft 2O to permit the rib 21, of said shaft, to convey material from the hopper into the drum. One end of the sleeve 23 is provided with a flange 24, which v is secured to the hopper, while the other end is formed with a flange 25, which is held in close engagement with the adjacent end wall of the drum by means of the flanged ring 26, secured to said end wall of the drum. Secured to the inner face of the said end wall of the drum, and projecting toward the adjacent end of the shaft 20, are the angle members 27 each having its inner end disposed at right angles and provided with a set screw 28, which binds against the shaft 2O to hold the shaft to the drum and permit the shaft to rotate with the drum. The

stem portion of the crank 18, is provided l with a flange 18', which is secured to the adjacent end wall of the drum so that upon rotation of the crank,`the drum will be r0- fated together with the shaft 20, thus feeding the flour.

It will thus be seen that upon turning the handle 18, the drum will be rotated and through the medium of the members 27, the shaft 21 will be turned also. At the same time the shaft 16 remains stationary.

Within the drum, and mounted on the shaft 16, are the Scrapers 29, the same being described in detail in the above mentioned patent.

l/Vhat is claimed is:

1. A flour sifter including a box, a hopper on one end of the box and having communication with the interior thereof, a rotatable drum within the box. a stationary shaft extending longitudinally through the box, drum and hopper, a means for rotating the drum, and a feeding means mounted on the shaft and connected with drum for feeding material from the yhopper to the drum, as the drum is rotated.

cent end of the drum for conveying flour from the hopper to the drum, a stationary shaft extending through the drum, hopper l5 and sleeve, sind feeding` ineens extending through the hopper and the sleeve and operated by the drinn.

In testimony whereof, I aiX my signature, in the presence of two Witnesses.
